Product features:
A81 aldehyde resin (also known as poly formaldehyde resin) product is colorless and transparent to the micro - yellow - resistant yellow - formaldehyde resin, also known as universal resin. The appearance is divided into fine granulation after regular semi-circular irregular small particles and without granulation process, as a special hard resin for solvent based coatings and inks, solvent-free coatings, waterborne coatings, powder coatings, resin modification and other system. A81 can obviously improve the resistance to yellowing, shorten drying time, increase the hardness, fullness and luster of the film, increase the solid content. Because of the low viscosity of A81, and reduce the use of organic solvents in the paint industry, reduce the environmental pollution caused by VOC emissions. Sengm formaldehyde resin A81 has good wettability of metal pigment and other pigment dispersion, while soluble in most organic solvents, so it is very suitable for oil soluble ingredients. In particular, the cost of general color can be reduced by more than 40%, which is far superior to the adaptation of low solvent similar products. A81 can also be used for powder coatings and chlorinated rubber paint, etc.. In short, the product performance has reached even more than similar foreign products, is a paint, ink and other industries use a very wide range of special resins.
solubility
Formaldehyde resin coatings A81 soluble in most solvents, such as alcohols, esters, ketones, ethers, aromatic solvents, aliphatic solvents, and similar foreign products are not soluble in aliphatic solvents, only a limited use of this solvent dilution. A81 aldehyde resin is insoluble in water.
Formaldehyde resin A81 applications
1, due to pigment wetting, the color is very light and excellent, especially suitable for preparation of formaldehyde resin A81 universal pigment paste, and its viscosity is very low, so it can be made of HISTEP pigment content color paste.
2, used for wood, metal, paper, polyurethane coating, on formaldehyde resin A81 in color, yellowing resistance, aging resistance, flexibility, adhesion, solubility and drying rate was obviously better than that of aldehyde and ketone resin.
3, because of good heat resistance, formaldehyde resin A81 is suitable for baking, especially because it does not produce any smell or make the resin discoloration, can significantly improve the resistance to flexion coating system etc..
4, used in the manufacture of alkyd resin, can reduce the viscosity of alkyd resin, increase the hardness, increase the luster, improve the drying. In the final phase of the synthesis of the aldehyde resin 5%-10% can achieve the desired effect. A81 aldehyde resin can be used for water - based alkyd paint modified by using appropriate emulsifier.
5, used in the manufacture of car repair paint, motorcycle paint, bicycle paint can improve the luster, improve the wettability of the paint, increase the hardness, resistance to yellow and weather resistance, shorten the drying time, etc., the proposed addition amount is 2%-6%.
6, the modified resin used in nitro paint, improve weather resistance to chemical properties, improve the fullness of nitro paint and disposable film thickness, enhanced resistance to yellowing, improve solid content and flow level, improve paint on solvent, especially benzene solvent dilution. Recommended to replace about 20% of nitro fiber.
7, for the modified resin of amino alkyd paint, can improve dry and accelerate the initial physical drying process is proposed according to the modified resin quality requirements to replace part of alkyd resin.
8, for alkyd / chlorinated resin paint modified resin, improve the compatibility of chlorinated resin (especially chlorinated rubber and chlorinated rubber) with alkyd resin, improve the gloss and chemical resistance, improve the chemical properties of the coating. It is suggested that the substitution rate of the modified alkyd / chlorinated resin coatings is not more than 10% of the total resin content.
9, especially suitable for the preparation of hot melt road marking paint, on the base material has excellent adhesion, improve the impact resistance, can significantly improve the system resistance to corrosion, good weather resistance. According to their own paint formulations and raw materials can be used to add about 20% or so of kr-a81 aldehyde resin or separate use of A81 as the base resin.
10, used in powder coating, improve the flow, and enhance the adhesion of the bottom material. In epoxy powder coatings, epoxy / polyester coatings, kr-a81 resin was used to replace 5%-15% with reactive resin, improve the physical and chemical properties of powder coatings.
11, ink, ink, pen for high-grade lake, copier toner, ink and other high-grade ink system, A81 formaldehyde resin can significantly improve the system yellowing resistance, chemical resistance, water resistance, the system gives excellent leveling and weatherability: quality and keep its good stability, no as far as the place for a long time stratification or product performance changes etc..
Special alert
1, aldehyde resin A81 color has a small change is very normal, will not have any effect on the product characteristics. The information and recommendations provided by the company are based on our current knowledge and experience, taking into account the many factors that will affect the processing and use, and recommend the manufacturer to carry out technical tests based on their own product formulation and the use of raw materials, and then determine the best or collocation solutions. Too many additions and uses will change the physical and chemical properties of the coatings, such as special requirements, and can be adjusted by self adjustment after many experiments.
2, A81 aldehyde resin can be based on its unique properties, can be extended to other ink, paint and other systems.
